Definitions
- the present invention a distributed automation system comprising an automaton programmable connected to programmable controllers and equipped with a central unit and couplers communicating by the backplane bus with said central unit, one of the couplers being connected by a bus to associated equipment.
- TCP / IP protocol It is known to use the TCP / IP protocol and software adapted to this protocol to communicate on different levels, via an Ethernet type bus for example, equipment of an automation network.
- the programmable logic controllers are then equipped a TCP / IP module or coupler. This solution makes it possible to federate different levels.
- the Java language is envisaged for automation at different levels for example at the level of supervision management and production management. We will refer by example to articles published in CiMax from May-June 97 or in Measures from May 98. This language Java has advantages regarding portability and object orientation as well as possibility to execute in the browser of a local station programs written in Java called "Applets" and imported across the network.
- the present invention aims to provide a hardware and software platform making the programmable controller active on an Intranet type network or its extensions by manipulation and / or production of manufacturing level information, ie "no involved ”directly in real-time control and defining an object model adapted to the current structure of automation. It makes it possible to integrate the automata programmable from the company's information system without calling into question the structure of the automated systems. This responds to the growing need for equipment integration of the production tool and management systems (Supervisors, Automated System of production, etc.).
- the system according to the invention is essentially characterized in that the coupler can communicate through a server function with the associated equipment under the TCP / IP protocol and is provided with a mass memory containing on the one hand objects so-called "PLC variables” software that manages access to PLC variables and on the other hand so-called “manufacturing” software objects transforming information from variable objects automata in manufacturing type information usable by associated equipment.
- PLC variables software that manages access to PLC variables
- manufacturing software objects transforming information from variable objects automata in manufacturing type information usable by associated equipment.
- the architecture shown in Figure 1 includes a PLC referenced API-1 equipped of a UC1 central unit. This controller communicates with other programmable controllers API-2, API-3, API-4 as well as with associated equipment SAP, M, C, P.
- the PLC-1 PLC is equipped with a server coupler CS1 which will be described below, the PLC-2 PLC being also equipped with a server coupler marked CS2.
- each programmable controller contains a program PAP application which is written in a usual automation language ("ladder", etc.) and manages inputs and outputs using so-called real-time control variables PLC variables which are marked VAR.
- the CS1 server function coupler of the API-1 programmable controller communicates via the backplane bus with the central unit UC1 of the PLC on which it is mounted and with the other couplers of this PLC.
- the PLC-1 PLC equipped with the CS1 coupler can communicate via, for example, a coupler with other PLCs programmable referenced API-2, API-3, API-4.
- the server coupler CS1 is provided with a connector allowing it to communicate via a bus B, under the TCP / IP protocol, with the associated equipment such as the SAP production management server, the dialogue P or computers C and M.
- each server coupler CS1 or CS2 supports a JAVA real-time operating system, a virtual machine that interprets “byte-code” JAVA (intermediate code obtained after precompilation by a JAVA compiler).
- This operating system is to ensure the connection of the CS1 coupler to the network TCP / IP type.
- Each coupler CS1 or CS2 is provided with a mass memory MS and a microprocessor.
- the coupler with server function CS1 of the PLC-1 PLC contains in its memory MS on the one hand, software objects called "with variable automata" referenced OV which manage access to VAR automaton variables and on the other hand, so-called “manufacturing” software objects referenced OM.
- This CS1 coupler supports a server for managing a set of pages of HTML type allowing the “management” of the coupler, in particular the display of the state of the coupler (On, Stop, error) and the modification of this state, the display of the state of the OM and OV objects of the coupler (On, Stop, error) and the modification of this state.
- An OM manufacturing object can easily be "connected" to different types of objects OV and therefore different types of protocols which allows the adaptation of the CS1 coupler to all types of industrial protocols.
- An OM1-S object which is executed on the CS1 coupler of API-1 controller can consume information produced by other OV-3 or OM-2 objects executed on a CS2 server coupler embedded in the PLC-2 PLC.
- OV objects "with PLC variables" can read or write the values of one or several VAR PLC variables using industrial control protocols. They pass the values of the PLC variables to OM objects according to the type of the PLC variable and or as required.
- the object OV-1 reads or writes by an operation marked 1 la value of a VAR1 PLC variable.
- OM1-S object can read or write by an operation marked 2 said value in the same form as that handled by the PLC variable. he can also read or write the value, by an operation 2a of figure 5, in another form than that of the PLC variable.
- the value does not change, the form (or also the dynamics) changes: for example the value instead of being coded on two bytes will be encoded on four bytes.
- the OM1-S object can also receive a relevant value in the form of an event.
- Each object linked to an OV PLC variable is assigned a unique symbolic name which is that of the automaton variable handled by it.
- the symbolic name and address associated (also called landmark) are saved in an SN name server implemented in the coupler CS1. Symbolic names and addresses are updated automatically, either when the name of a PLC variable is changed or when the address of the PLC variable.
- Each object called “manufacturer” consists of an object such as OM1-S, located on the server coupler CS1 and an OM1-C image object located on a client station such as P, C, M or SAP. It generates, from the values of the PLC variables provided by an OV object or by an OM object "manufacturer" type information, ie information intended by example to the factory information system.
- Such an OM object can exchange, with several industrial programmable controllers.
- Manufacturer level information 3 can for example be a generated alarm by a production machine, a business data (for example the number of cars or the number of bottles), a remote message via email, a PLC / server connection information, system diagnostic information, alarm management information, an alarm message according to values taken by certain PLC variables or relational database management information or management information for archiving events on relational databases, information managing the display of a partial machine view.
- Each OM "manufacturing" object is assigned a unique symbolic name stored in the SN name server and suitable for use on the network.
- the OM1-C client object is the "proxy" or image of the OM1-S server object.
- the localisation OM1-C image object depends on its use.
- the OM1-C object is stored in the persistence base BP of the server coupler CS1.
- the object OM1-C is used it is executed on a client machine of the server coupler CS1, after unloading, via the network, from the BP persistence database.
- This BP persistence database contains the state OV and OM objects (including the OM-C client object for the latter).
- the OM1-C client object offers a so-called OM object management view (state of object, position, parameter). It can render optional services depending on the nature even of the OM object, such as the interface with external systems (SAP), a tabular alarm view for an alarm service, a block diagram, etc.
- the OM-C client object can take the form of HTML pages, "applets”, “Beans” (Java software component) and or other software components.
- OM manufacturing objects deliver relevant data in the form events (producer / consumer model) and ensure the consistency of names of manipulated objects. It is the server coupler CS1 which maintains the database of names, other software being connected to this server.
- a PLC programming workshop APA sends the list of modifications to the name server SN each time a modification of the PLC program modifies a PLC variable linked to an OV object.
- the OV-1 and OV-2 objects receive information 1 and 5 concerning PLC variables of the UC1 central unit. These OV-1 and OV-2 objects deliver information to the OM1-S server part of the manufacturing object. In addition this object OM1-S can receive information from OV-3 and OV-4 objects from another API-2 controller. The part OM1-S server of the manufacturing object generates information of the manufacturing type 3.
- the OM1-S server object transmits information 3 of the manufacturing type by an exchange referenced 7 to the OM1-C client object.
- OM1-S object transmits synchronization information to the central unit UC1.
- a client workstation such as P, C, M or SAP transfers via a browser or other means , by an exchange referenced 6, via network B, the client part of the object OM1-C.
- This part client of the OM1-C object is stored on a client workstation either punctually (in the case of a web browser type connection for example), either permanently on a SAP server for example.
- the software 10 of an external application executed on the client computer receives by an exchange 8 of the manufacturing type information.
- the SAP server is queried by the OM object or the SAP server returns the data requested by OM.
